How To Grow Rhubarb In A Container: Tips And Tricks

How To Plant Rhubarb Crowns


Growing your own rhubarb can be a rewarding experience, but what if you don’t have enough space in your garden? Don’t worry, you can still grow rhubarb in a container! In this article, we will guide you through the process of growing rhubarb in a container, step by step.

Choosing the Right Container

The first step in growing rhubarb in a container is choosing the right container. You want a container that is at least 12 inches deep and 18 inches wide. The container should also have drainage holes to prevent waterlogging. You can use a plastic, ceramic, or clay pot, but make sure it’s sturdy enough to support the weight of the plant.

Preparing the Soil and Planting

Once you have your container, it’s time to prepare the soil. Rhubarb likes well-draining soil that is rich in organic matter. You can mix compost, peat moss, and perlite to create a soil mix that is ideal for rhubarb. To plant your rhubarb, fill the container with the soil mix and plant the rhubarb crown in the center of the container. Make sure the crown is about 2 inches below the soil surface. Water the plant thoroughly and place it in a spot that gets at least 6 hours of sunlight per day.

Watering and Fertilizing

Rhubarb needs regular watering to thrive, especially during the growing season. Water the plant deeply once a week, or more often if the soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. You can also fertilize your rhubarb to promote healthy growth. Use a balanced fertilizer, such as a 10-10-10 or 20-20-20, and apply it once a month during the growing season.

Harvesting Rhubarb

Once your rhubarb plant is established, you can start harvesting the stalks. Wait until the stalks are at least 12 inches long before harvesting. To harvest, grasp the stalk near the base and pull it away from the plant. Avoid cutting the stalks with a knife, as this can damage the plant.

Maintaining Your Rhubarb Plant

To keep your rhubarb plant healthy, you need to maintain it properly. This includes removing any dead or damaged leaves, as well as dividing the plant every few years to prevent overcrowding. You can also cover the plant with mulch during the winter to protect it from the cold.

Common Problems and Solutions

Like any plant, rhubarb can be prone to certain problems, such as pests and diseases. Common pests that affect rhubarb include aphids, slugs, and snails. To control these pests, you can use insecticidal soap or diatomaceous earth. Rhubarb can also be affected by diseases such as crown rot and powdery mildew. To prevent these diseases, make sure you plant your rhubarb in well-draining soil and avoid overwatering.


Growing rhubarb in a container is a great way to enjoy this delicious vegetable even if you don’t have a lot of space in your garden. With the right container, soil, and care, your rhubarb plant can thrive and provide you with a bountiful harvest for years to come.
